To (ZZZ whom'itmay concern:

Be it known that we, OSCAR B. MUELLER and DANIEL H. BUELL, citizens of the United States, and residents, respectively, of New Rochelle, VVestchester county, New York, and Marietta, county of Washington, Ohio, have invented certain newand useful Improvements in Means for Supporting Sheaves, of which the following is a specification' Our invention relates to a new and improved means for guiding a cable in its passage into a pipe line for use particularly with pipe cleaning devices, or in guiding a cable in its passage from the pipe line to the drum upon which it is wound.

In the pipe cleaning art it has been found that where a cable is attached to a pipe cleaner and is permitted to pass i n and out of the pipe without any guiding means the friction'between the end of the pipe or the bell of the pipe and the cable tends to wear out said cable, this necessitating frequent renewals and replacing of cables. This by the use of our invention we overcome. It has also been found that in some locations, for instance, where the outlet of the pipe is near an obstruction that the drum upon which the cable is wound has to be located in such a position that the cable pulls against the side or inner end of the pipe line. This, of course, is not only detrimental to the cable, but is also detrimental to the end of the pipe line. This we also overcome with our invention.

In the drawings, Figure 1. shows our invention in operation; Fig. 2 shows a View of our removable frame which supports the sheave forguiding the cable; and Fig. 3 is an end view of Fig. 1 with the pipe removed.

A is a section of ordinary pipe having a bell, A at one end thereof.

B is a cable which is passing into or out of the section of pipe line and to which is attached apparatus used in pipe cleaning.

lVe'provide a frame composed of the side arms 1, 1, held together by means of bands or cross arms 2, 3. .The cross arms or bands 2, 3, are preferably made as shown so that they will pass on opposite sides of the pipe A at some distance apart. These bands 2, 3 are preferably made so that they will fit the pipe A. As shown in Fig. 1 it will be noted that arms 1, held in place by the bands 2, 3 are located at a point just below the center of the pipe as the band 3 is longer than the band 2. This is arranged in this manner so that the set screws 9, 9 located in the arms 1 when in engagement with the surface of the pipe A will tend to hold the frame in position without permitting any upward movement. The band 2 is extended so as to form lugs 1 1 in which are placed the set screws 15, 15, which with set screws 9, 9, tend to hold the frame rigidly in place. In the preferred form shown we have also shown the arms 1 as being a greater distance apart between the bands 2 and 3 and between the band 3 and the axle 5 of the sheave than they are at the bands 2 and 3 or at the axle 5. This is done so that the frame-may be readily passed over the bell A, of the pipe. At the outer end of the frame, but preferably integral therewith, we provide arms 1 which are arranged at an oblique angle to the arms 1, l, of the frame. These arms 1 are provided with a long open slot at which slot at its lower side is provided with notches 1, A and 41. e provide an axle 5 which is mounted in the slots 4: of the arms 1 so that it may be freely moved from one to another of the notches 49,4" and 4: or may be arranged so that it will rest in the notch l of one of the armsl and in the notch 4 of the other arm 1%, the object of this being so that the sheave 6 which is loosely mounted upon the axle 5' may be arranged at an angle to guide the cable from the drum irrespective of the position of the drum into the desired position in the pipe line. Upon axle 5 we provide blocks l having set screws 7 which are adapted to be'moved together so as to hold the sheave 6 in any position on the axle, that is, it -may be held in the center of the axle or it' may be held to the right or left of the center as far. as desired.

We have found that the cable B will sometimes have a tendency to leave the sheave 6 and to prevent this we have mounted the roller 13 loosely on the shaft 12 held in place above the sheave by the arms 10, 10. As will be seen in Fig. 3 these'arms 10, 10 are held in place on the axle 5 between the nuts 8 and 11 in such a way that the roller 13, if desired, may be swung around below the sheave or may be held in position above the sheave as shown in Fig. 1 by the tightening of the nuts 11. This roller 13, extending substantially the entire length of the axle 5, will serve to prevent the cable B from leaving the sheave no matter what position the sheave is in on said axle. By having the roller 13 supported by the arms 10 which are mounted on the axle 5 the roller is always parallel to the axis of rotation no matter what position the axlemay be in in relation to the pipe line.

In operation our device is used as follows: The frame is passed over the bell, the bell passing between the bands 2, 3, after which the frame is placed in the position shown in Fig. 1, that is, with the band 2 on the under side of the pipe and the band 3 on the other and the arms 1, 1 parallel with the pipe. The cable B is then placed in position on the sheave 6 and the device is ready for operation. As will be seen, with the device in the position shown in Fig. 1, the cable B will be guided into the middle of the pipe line A. If it is desired to have the cable guided to the right or left side of the pipe line it is merely necessary to shift the sheave 6 and hold it in position by means of one or both of the blocks 7. If the drum upon which the cable B is being wound or from which it is being unwound is not directly in front of the pipe, but is to one side or the other, the axle 5 may be placed in a position so that the sheave 6 will be at an oblique angle to the pipe line and thus guide the cable B to the desired location.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is,

1. The combination of a sheave and means for supporting said sheave, said means composed of arms connected together by means adapted to partially encircle the body to I which it is to be attached, enlarged spaces between said arms at points between the means adapted for encircling the body.

2. The-combination of a body, a cable, a sheave for said cable, a supporting frame for said sheave consisting of arms adapted to lie parallel to the length of said body, .bands partially encircling said body on opposite sides separated by a distance not less than the diameter of the said body.

3. In combination with a pipe fitting, a

sheave, a cable adapted to pass over said sheave, means for supporting said sheave in position adapted to engage with said fitting. on opposite sides but in different planes, consisting of arms arranged on opposite sides of said fitting and bands partially encircling said fitting on opposite sides there- Gopies of this patent may. be obtained for five cents each, by addressing the Commissioner:

of, one of said bands connecting said arms at a point intermediate the sheave and the point where the other band connects with said arms.

4. The combination of a body, a cable, a sheave for said cable, a supporting-frame for said sheave having bands partially encircling said body on opposite sides, said bands being separated by a distance not less than the diameter of said body,substantially as set forth.

5. In combination with a sheave, a supporting frame consisting of arms having means for supporting said sheave, a band connecting said arms and adapted to engage with one side of the body to which the sheave is attached, another band arranged to engage the opposite side of the body to which the sheave is attached connecting said arms at a point intermediate the first band and the means for supporting the sheave, substantially as set forth.

6. In a sheave-supporting frame, the combination of a sheave, an axle for said sheave, arms adapted to support said axle, bands arranged to engage the opposite sides of the body to which the sheave is attached connecting said arms together arranged on opposite sides of said arms, one of said bands connecting with said arms at a distance intermediate the other band and the axlesupporting means.

7. In combination with a sheave, a supporting frame having an axle for said sheave, a band connected with said supporting frame and adapted to partially encircle the body to which said sheave is to be attached and lying on one side of the body, a separate band adapted to lie on the other side of the body to which the sheave is to be attached and to partiallv encircle said body; said last-mentioned band being connected with said supporting frame ata point intermediate the first band and the axle for the sheave.

In testimony whereof, we have signed our names to this specification, in the presence of two subscribing witnesses.
